## 1 + 4 = 5

2 + 5 = 12

3 + 6 = 21

8 + 11 = ?

The Viral 1 + 4 = 5 Puzzle ā Correct Answer Explained below

##### Show answer

**Correct Answer: 8+11=96Ā **

Ā

**Solution: 1**

If you look at first 3 Equations **a + b means a + ab**

a+b => a+ab

Let see now how it works for all equations ,

1 + 4 means 1 + 1(4) = **5**

2 + 5 means 2 + 2(5) = **12**

3 + 6 means 3 + 3(6) = **21**

now will apply same formula for the last equation **8+11=?**

8 + 11 means 8 + 8(11) = **96**

**So final answer isĀ 96 is proved.**

**Solution : 2**

1 + 4 =Ā **5****5Ā **+ 2 + 5 =Ā **12****12**Ā + 3 + 6 =Ā **21****21**Ā + 4 + 7 =Ā **32****32**Ā + 5 + 8 =Ā **45****45**Ā + 6 + 9 =Ā **60****60**Ā + 7 + 10 =Ā **77****77Ā **+ 8 + 11 =Ā **96**

Once again we get the answer of 96, that’s surprising!

**Alternate method :Ā **

a+b= a+b(sum of the previous equation)

**1 + 4** = **5.**

**2 + 5** (plus the previous sum of 5) = **12.**

**3 + 9** (plus the previous sum of 12) = **21.**

same logic will apply for last equation also

**8 + 11** (plus the previous sum of 21) = **40.**
